Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified adam optimizer algorithms" » "modified adam optimized algorithms", "modified adam optimized algorithm", "modified adam optimization algorithms", "modified df optimizer algorithms", "modified near optimizer algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adam optimizer algorithms") OR ("modified multiobjective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam optimizer algorithms\") OR (\"modified multiobjective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified adam optimizer algorithms ) OR ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam optimizer algorithms") OR ("modified multiobjective optimization algorithm"))*.
